After these lights interact with objects or the environment, such as reflection, transmission, absorption, etc., their properties, such as intensity, wavelength, polarization, etc., will change; the optical sensor can sense these changes and transmit them as input signals to the frequency modulation unit 400 to vibrate the culture tube 120 to achieve the frequency of regulating the movement of Haematococcus.

[0041] Furthermore, the monitoring tube 310 is a tube made of transparent material and a pair of electrode rods 322 are arranged on its inner wall. The electrode rods 322 are made of metal sheets and cross the breeding tube 120. The positive and negative poles of the optical sensor 320 are connected to brushes that are in sliding contact with the pair of electrode rods 322 so that the optical sensor 320 can obtain electrical energy to work. The outer wall of the monitoring tube 310 is annular and has a plurality of support blocks 311 at equal intervals. The plurality of support blocks 311 are fitted together with the breeding tube 120 to ensure that the monitoring tube 310 is stably arranged.

[0042] Specifically, the frequency modulation unit 400 includes a striking tube group 410 that moves synchronously with the optical sensor 320 and a servo motor 420 for driving the striking tube group 410 and the transmission group 340 to rotate; the striking tube group 410 includes a pair of striking shafts 412 pointing to the inner side walls of two adjacent breeding tubes 120, a shifting block 413 for shifting the striking shafts 412 to extend, and a double-headed motor 414 for driving the pair of shifting blocks 413 to rotate;

[0043] A solar panel for providing electrical energy is installed on the top of the pipe support rack 110, that is, to provide power for the optical sensor 320, the servo motor 420 and the double-headed motor 414 to make them work; a control unit and a wireless transmission module connected to the control unit and the optical sensor 320 are provided on the connecting pipe 200, wherein the output end of the control unit is connected to the control interface of the double-headed motor 414, and the control unit is a microprocessor; the optical sensor 320 perceives changes in the external environment, and the control unit processes and responds to the sensor signal, thereby realizing precise control of the electrical appliance, which is a prior art and will not be repeated here.

[0044] Furthermore, a sleeve 321 is sleeved on the rear end of the optical sensor 320, and the bottom of the sleeve 321 is threadedly connected to the monitoring screw rod 330, so that the optical sensor 320 has sufficient operating space; a slot 3211 is provided on the side of the sleeve 321, and the slot 3211 is slidably engaged with a pair of electrode rods 322, and a threading port 201 is provided on the side of the connecting tube 200, so that the pair of electrode rods 322 do not contact each other, and a wire is connected to the rear end of the electrode rod 322, and the wire passes through the threading port 201 and is sealed with a sealant, so that the optical sensor 320 obtains electricity; a plug 331 is tightly sleeved in the sleeve 210, and the end of the monitoring screw rod 330 is plugged and rotated with the plug 331, and the sleeve 210 is blocked by the plug 331 to seal the inside of the monitoring tube 310, so that the red algae can move between the cultivation tube 120 and the monitoring tube 310.

[0045] Specifically, the transmission group 340 includes a transmission ring 341 sleeved on the outer wall of the connecting tube 200, a transmission sleeve 342 magnetically attracted to the transmission ring 341, and a transmission plate 343 fixedly connected to the end of the monitoring screw 330.

The transmission sleeve 342 is located inside the connecting tube 200, and a magnet 3411 is embedded on one side of the transmission ring 341; the transmission sleeve 342 is an iron sleeve coated with an anti-rust coating, and the transmission sleeve 342 is magnetically attracted by the magnet 3411 to drive it to rotate around the center of the transmission ring 341. Since the monitoring screw 330 does not coincide with the central axis of the transmission ring 341, the monitoring screw 330 is driven to rotate by the sleeve connection of the transmission sleeve 342 and the transmission plate 343, and then the sliding sleeve 321 is driven to move axially along the monitoring screw 330 under the guidance of the electrode rod 322, that is, the optical sensor 320 is driven to move.

[0046] Furthermore, the servo motor 420 is installed inside the pipe support frame 110 and its output shaft end is coaxially connected with a transmission screw 421 for guiding the movement of the pipe striking group 410.

Both ends of the transmission belt 422 pass through the pipe support frame 110 and are sleeved with two transmission rings 341; that is, the servo motor 420 drives the transmission screw 421 to drive the pipe striking group 410 to move along its axial direction, and at the same time drives the transmission belt 422 to drive a pair of transmission rings 341 to rotate, thereby driving the monitoring screw 330 to rotate, and then driving the optical sensor 320 and the pipe striking group 410 to perform monitoring and frequency modulation movements synchronously and in the same direction;

[0047] A support sleeve 423 is sleeved on the front end of the transmission screw rod 421 , and the support sleeve 423 is sleeved and matched with the adjacent servo motor 420 , so as to support the transmission screw rod 421 to rotate stably.

[0048] Specifically, a slider 411 is disposed below the pair of striking shafts 412, a threaded hole 4111 is provided on the middle side wall of the slider 411 for threaded connection with the transmission screw 421, a ring is provided on the middle top surface of the slider 411, and the ring is sleeved and matched with the double-headed motor 414;

[0049] A pair of limiting rods 112 are embedded between two adjacent pipe support racks 110 and between each pair of breeding pipes 120. The left and right side walls of the slider 411 are provided with through holes which are sleeved with the limiting rods 112, so as to guide the slider 411 to move axially along the transmission screw 421. The inner side wall of the limiting rod 112 is embedded with an electrode rod 322, and the positive and negative poles of the double-headed motor 414 are provided with brushes which are in sliding contact with the two electrode rods 322 in the pair of limiting rods 112, so that the double-headed motor 414 obtains electricity to work.

[0050] Furthermore, the left and right ends of the slider 411 are fixedly connected with a stopper 4122, which is annular and has a center hole that is inserted and slidably engaged with the striking shaft 412, so as to guide the lateral movement of the striking shaft 412; a limit block 4121 is provided at the inner end of the striking shaft 412, and a spring 4123 is provided on the outside of the striking shaft 412 and between the stopper 4122 and the limit block 4121, and the spring 4123 is used to rebound the striking shaft 412 and reset it; the shift block 413 is a round block and has an inclined surface at its outer end, and the inner end of the striking shaft 412 is aligned with the bottom of the inclined surface of the shift block 413 and slides in contact with it; that is, after the double-headed motor 414 drives the shift block 413 to rotate one circle, the inclined surface of the shift block 413 is used to push the striking shaft 412 to hit the outer wall of the cultivation tube 120, so that the Haematococcus inside it vibrates and continues to move.

[0051] Furthermore, a limiting ring 220 is symmetrically sleeved on the middle outer wall of the connecting pipe 200, and the transmission ring 341 is located between a pair of limiting rings 220, which plays a limiting role to ensure that the contact between the transmission belt 422 and the transmission ring 341 is stable; avoidance holes 113 are opened on the left and right side walls of the support pipe rack 110, and the height of the avoidance holes 113 is smaller than the diameter of the transmission ring 341 and the pulley, so that the transmission belt 422 is tightened between a pair of transmission rings 341 and drives them to rotate normally.

[0052] When the device for monitoring and modulating the movement state of Haematococcus pluvialis in a photobioreactor of the present invention is working, the servo motor 420 is started regularly to drive the optical sensor 320 to move axially in the culture tube 120 and to drive a pair of striking shafts 412 in the striking tube group 410 to move outside the culture tube 120, thereby sensing the change in light intensity on the inner wall of the tube and taking it as an input signal. The control unit analyzes and processes the signal to determine its relationship with the light intensity threshold. When the control unit obtains a result weaker than the threshold, it decides to convert it into a control signal and outputs it to the double-headed motor 414 through the control interface, thereby driving the striking shaft 412 to strike the culture tube 120 so that the Haematococcus pluvialis on the inner wall does not adhere to the wall, that is, the frequency of the movement of the Haematococcus pluvialis is adjusted by vibrating the culture tube 120.
